To aZZ whom it may concern: yoke, which rest on the upper washers, and Be it known that I, STANLnr J. Vnsnm', 1n the loading or jolting of the body coma citizen of the United States, residing at press the interposed coil springs 23, are Cedar Rapids, in the county of Linn and rounded on their washer-engaging faces, 6 6 State of Iowa, have invented certain new and since it be evident that the yoke must rock useful Improvements in Shock Absorbers; a little as it moves up and down.

This invention relates to shock-absorbers The construction avoids the necessity of for motor vehicles in which the body springs using a linked connection of the leaf spring are mounted parallel with the axles, and with the lever of the shockabsorber, since 7 embodies certain improvements in the type the outward and downward movement of of shock-absorbers for which Letters Patent the leafspring supporting pocket correwere issued to me on the twelfth day of sponds with the natural movement of the July, 1921, No. 1,384,545. eye of the leaf spring, as the latter straight The object of this invention is to simplify ens and extends under superimposed pres- 7 so the construction of the shock-absorber, more sure.
